Backlinks are links on websites other than your own that go back to a page on your website. Backlinks are also called inbound links because they represent another website's traffic coming to your own site. The quality and quantity of your backlinks can help you rank higher in search engines such as Google and Bing.

Backlinking, or link building, involves strategically obtaining links from other websites to your own, boosting your website's authority and ranking in search engine results. To effectively implement a backlinking strategy, focus on creating high-quality content, actively seeking opportunities, and building relationships with other webmasters. 

In SEO, anchor text refers to the clickable text within a hyperlink, which is the visible part of a link that users and search engines use to understand the context of the linked page. It's the text that you click on to navigate to a different webpage or section on the same page. 

Building backlinks involves strategically getting other websites to link to your site, which improves your search engine ranking and website credibility. This can be achieved through various methods, including creating valuable content, guest blogging, outreach, and analyzing competitor link profiles.
